September update:
DC Sales - Top 300 (Jan-Sep) 2014 - 19,651,345 estimated units.
DC Sales - Top 300 (Jan-Sep) 2013 - 21,302,646 estimated units.
And here are the figures for 1997-2012:
2013 - 28,184,085 estimated units
2012 - 29,602,125 estimated units
2011 - 26,522,201 estimated units
2010 - 23,528,000 estimated units
2009 - 24,126,336 estimated units
2008 - 25,760,378 estimated units
2007 - 29,597,217 estimated units
2006 - 30,243,575 estimated units
We'll probably come out of 2014 at about 27 million.
Sales are dropping (until the next big thing - maybe whatever is coming in 2015), but still way above where they were before.
My point being that "loyal fans" either:
a) aren't really all that loyal or
b) aren't really all that plentiful.
